Phryganistria chinensis, a stick insect, is the longest out of the 807,625 known insects in the world. Discovered in China in 2014, it measures more than 60cm, proudly beating the previous record holder, a stick insect from the Phobaeticus chani species of Malaysia, by almost six centimetres. The insects feed almost exclusively on plants and protect themselves from predators by merging into their surroundings. The lanky beasts have their unusual bodies to thank for this: they mimic dead branches.
(The stick insect pictured above is of the Achriopetra fallax genus.)
